haproxy) with logs:

Redis and haproxy working fine (I test it by many attepts - echo ping|ncat
localhost 6380)

At tcpdump all attemps from kamailio have:

*1

$4

PING

+PONG

*2

$6

SELECT

$1

0

+OK



my kamailio 5.0.4 config:
modparam("ndb_redis", "server", "name=redis;addr=127.0.0.1;port=6380")

my haproxy 1.5 config:
backend bk_redis
        mode tcp
        option tcp-check
        tcp-check connect
        tcp-check send PING\r\n
        tcp-check expect string +PONG
        tcp-check send QUIT\r\n
        tcp-check expect string +OK
        server sipkazan 192.168.107.195:6379 check inter 1s
        server local 127.0.0.1:6379 check inter 1s backup
